Stawer friend first of all how sorry I am for the death of this great partner, he was a great support as you mentioned, and I know it is difficult to cope with the loss of someone as important and valuable as he was.
I am also sorry to hear the news about your mother, I hope with all my heart that she is well and gets better soon.
Now, my captain, it is not good for you to prioritize work, we really know that these are very difficult times that you are going through, and we all understand, and at the same time we want the best for you, just as you prioritize us, we also prioritize you and we want you to be well no matter how much time you need, be it a week, a month, a year, two years, whatever, we only want the best for you, so do not take work so seriously and give yourself some time for yourself, so do not worry about us, worry about you.
Take care of yourself, yes? It may be hard but you need to do it.
Best wishes to you, Stawer <3
